Canon EF-S 10-22mm geometry comparison
|To measure and compare the Canon 10-22mm’s geometric distortion we photographed a test chart consisting of a grid pattern, using it and a number of rival lenses.The lenses were tested at their widest focal lengths with an aperture of f8 using a Canon EOS-400D in Aperture Priority mode.The images were analysed with Imatest using 5th Order line calculation and the full areas presented here at a reduced resolution.|
The image above was taken with the Canon EF-S 10-22mm at 10mm f8. Barrel distortion was measured at 3.59% which is remarkably low considering the extreme wide angle coverage at this focal length. It’s roughly comparable to the distortion you’ll experience with the EF-S 18-55mm when it’s zoomed-out, and a significant improvement over the EF-S 17-85mm at 17mm. It’s also worth comparing against the EF 17-40mm tested on a full frame body, which delivers coverage almost as wide (17mm actual versus 16mm equivalent). In our EF 17-40mm review, geometric distortion at 17mm on an EOS 5D was measured at 6.39% – considerably higher. An impressive result here for the EF-S 10-22mm.

The lenses were tested at their longest focal lengths with an aperture of f8 using a Canon EOS-400D in Aperture Priority mode.To measure and compare the Canon 10-22mm’s geometric distortion we photographed a test chart consisting of a grid pattern, using it and a number of rival lenses.
The images were analysed with Imatest using 5th Order line calculation and the full areas presented here at a reduced resolution.
The image above was taken with the Canon EF-S 10-22mm at 22mm f8. While most lenses exhibit pincushion distortion when zoomed-in, the EF-S 10-22mm showed barrelling. This however isn’t that surprising considering the lens is still quite wide even when zoomed-in, and more importantly the actual degree of distortion at just 0.24% is very low. Judging from this and the above result, the EF-S 10-22mm is a good performer when it comes to geometric distortion, which will come as a relief to anyone shooting buildings indoors or out.
